x86: Treat relocation against IFUNC symbol as FUNC
When resolving a relocation against IFUNC symbol in a SHT_NOTE section
without SHF_ALLOC, we treat it as relocation against FUNC symbol since
it needs the address of IFUNC symbol, not the address returned by IFUNC
function.

* elf32-i386.c (elf_i386_relocate_section): Treat relocation
against IFUNC symbol in SHT_NOTE section without SHF_ALLOC as
relocation against FUNC symbol.
* elf64-x86-64.c (elf_x86_64_relocate_section): Likewise.
